1. INTRODUCTION
In our day to day life we are dealing with electricity as well as so many electrical equipments. In this electrical equipment the household appliances play a major role.
So the fault occurring with them is also a major problem. Generally the fault seen is the breaking of wire inside the two layer or three layer cables or the short circuit between them. Portable loads such as video cameras, halogen flood lights, electrical irons, hand drill, grinders, and cutters are powered by connecting long 2- or 3-core cables to the mains plug. Due to prolonged usage, the power cord wires are subjected to mechanical strain and stress, which can lead to internal snapping or short circuiting of wires at any point. In such a case most people go for replacing the core/cable, as finding the exact location of a fault of the wire is difficult. In 3core cables, it appears almost impossible to detect a fault portion of the wire and the point of break or short circuit without physically disturbing all the three Wires that are concealed in a PVC jacket.
Invisible Broken Wire Detector:
The circuit presented here can easily and quickly detect a faulty wire and its point of open circuit or short circuit in 1-core, 2-core, and 3-core cables without physically disturbing the wires. The circuit present here can work in the two modes of operation. One is the mode of invisible broken wire detector and the second as a short checker. The invisible broken wire detector exactly find the location of the fault due to the breakage of wire inside the cables while the second circuit will find whether the fault is a short circuit fault which is happening due to the burning of insulation inside the cables. Hence this circuit offers a simple and better way of finding the faults in the household appliances.
